Application led August 7, 1916; Serial N o. 113,639.

l citizen of the United States, residing at Omaha, in the lcounty of Douglas and State of Nebraska, have inventedcertain new and useful Improvements in Steam-Vulcanizers, of whichr the following is a specification.

A This invention relates to improvements in steam vulcanizers for use in repairing automobile tires or similar articles of rubber.

One of the objects of the invention isto provide a vulcanizer which may beused to advantage in mending both outer tires and inner rubber tubes, the same to consist of few parts and of simple construction so that it may be 'used by any person of 'ordinary skill or experience for the purpose named. Another object is the provision of an apparatus of this class which may beinanu-l factured at slight expense, comparatively, and having its parts so arranged that heat Amay be generated quickly and with the least expenditure of fuel.

A further object is to provide a vulcanizer soarranged that all parts may be used at the same time, and when but one or more parts are tobe used the steam may b e shut off from the others.

Another object is to provide resilient -means whereby a pressure may be automatically maintained while the inner tubes are being vulcanized.

The apparatus includes, briefly, a flat'vulcanizing platform, a boiler or casing and a heating chamber all of which may be formed to advantage as a single metallic-casting, certain contact-blocks being provided and so arranged that they may be suspended from swinging arms and moved above and depressed upon the platform for the purpose of vulcanizing the rubber, and may be swung to an'unobtrusive positionhwhen not in use.

Also it includes a standard or frame for use,

in supporting the tubes while being vulcanized, also -certain tire molds provided with segmental chambers vcommunicating with the boiler, and so arranged that the tires maybe quickly secured or released, a safety valve, steam gage, and a gas pipe arranged for heating also being shown.

lVith the foregoing objects in view the invention presents-a novel construction, combination and arrangement of' parts as de- Fig. 4 is a vertical section on line 4-4 of 65 Fig. 1 showing the steam chambers.

Figs. 5 and 6 respectively are plan and side views of ,a spring washer.

Fig. 7 is an enlarged vertical sectional .view of a swinging arm member, the contact-block being in section, a part of an l' inner tube being added and in section. `Fig 8 isa side View illustrating theparts shown in Fig. 7. y

Fig. 11 is an end view of the tire form.

Fig. 13 is an end view of the form shown in Fig. 12.

' Fig. 14 is a side view of a compression plate.

Fig. 15 is a broken away View showing a modified form for the bottom of the boiler, numerous pipes or vertical projections being substituted for the horizontal steam pipes.

Fig. 16 is a vertical sectional view on the l line -16 16 of Fig. 15.. Fig. 17 is a plan'view of a sustaining-plate or brace bar.

Referring'now to the drawing for a more particular description, numeral 1 `indicates a casing or container which may be conj structed to advantage of a single metallic casting to provide upon'its upper face a flat, elongated, rectangular, vulcanizing platform 2, a compartment 3 below and contiguousto -100 said platform for containing water, said casj ing having a longitudinal channel'flbelow the compartment 3 formed by the two extensions 5, vwhich project downwardly from the 1ks)ides of the casing to form a heating cham- 105 Disposed parallel in the channel 4 and i bmmunicating with the boiler near the ends lthereof are water pipes 6.' Steam may be generated in the boiler, by use of gas or other suitable fuel, gas preferably being used in connection with a perforated pipe-- burner 7 best shown in Fig. 1.

The boiler is provided with a steam gage 8, and a safety blow-out valve 9, by regulating which the certain steam pressure or heat best adapted for vulcanizing may be maintained. To facilitate the placing of water in the boiler a funnel 10 is attached thereto.

At 11 are indicated tire molds. They are formed of a single hollow metallic casting preferably of U-shape in`cross-section permitting steam to circulate therein, and operating to. distribute thev heat uniformly. The steam is introduced from the boiler through pipes '13 and returned to theboiler through the connections 12, said members 12 and 13 being provided with cut-oli' valves to effect a savingof heat, when either or both of molds 11 are not in use with the other parts of the apparatus.

In order that the various sizes of tires may be repairechthe vulcanizer is. provided with forms of various sizes and shapes to correspo-nd to the standard sizes of tires. Inoperation, to vulcanize a tire 14, the channel or interior part of the tire is first filled with a backing, such as coiled springs orthe like (not shown). The metallic form 15 being in place within the mold, the tire is placed within the form, the pair of tire beading-forms 16 are then put in place and covered with a bearing-plate 17.' A brace-bar 18 having a key bolt 19 threadedl in the bar is then put in place and a required pressure applied to the tire by rotating the key-bolt. The bar 18 is provided with a recess z opening on one of its ends, and near its opposite end is provided with a recess b opening on one of its sides. The bar is secured upon the mold 11 by means of the pair of bolts 20 which traverse said recesses and are threaded in the upright sides of the tire mold. It is obvious that by varying the sizes and shapes of members 15 and 16 -the several different sizes of tires may be vulcanized.

O n one side of the vulcanizer platform and integral therewith are projections or lugs 33 more clearly shown in Figs. 7 and 8.

These lugs are each formed with a vertical aperture to provide a bearing for the shank 28 of a curved arm 21. Threaded into the shank is a cap screw 22 serving as a keeper for the washers 23 and 23 said washers being interposed between the head of the capscrew and the bottom of the lug. Between the washers 23 and 23 and encircling the shank bf each arm is a spring washer'24 best shown in the enlarged detailFigs 5 and 6. Washers 24 are preferably constructed of spring steel, each being incised to provide two free ends, and bent adjacent l to its ends to extend outwardly of its sides as best shown in Fig. 6. This washer serves to create tension on the inner tube 25 (Figs. 7 8,) while said tube4 is being vulcanized, thus accomplishing one o-f the objects of the invention.

To vulcanize an inner tube 25, it is placed between the platform and a plate 26, said plate being pressed downwardly by the keybolt 27 which is threaded through a bushing at the upper end of arm 21. This pressure causes the arm 21 to move upwardly a limited distance and thereby compressing or flattening the spring washer 24. vSince the rubber will expand from the action of heat during the operation of vulcanizing, the spring washer 24 will cause a pressure to bey maintained upon the tube during said eX- pansion without attention of the operator.

At 29 is indicated a supporting-frame or standard, its ends being thrust into sockets c formed in the projections, this being ,useful for supporting the tubes while they are being vulcanized.

The brace bars 30 best shown in Figs. 3 and 4 operate to maintain the tire molds 11 in rigid relation with the casing. Legs 31 are preferably employed for supporting the casing, these being disposed inA suitable ysockets formed in the projections 32, said projections being a part of the casing.

Figs. 15 and 16 illustrate -a modification in the arrangement of partsin the heating chamber, believed to be within the scope of the invention, comparatively short vertical pipes 34 being'substituted for the horizontal pipes above described. The pipes 34 may be of any desired diameter and length theirfree ends being closed by caps 35, their upper ends projecting through the bottom of the boiler. These pipes may be arranged in rows o-r in staggered relation at the sides of the burner 7 as shown in Fig. 15. This arrangement facilitates heating and less fuel will be required.

Having fully described the several parts in detail, a further explanation relating to operation is not necessary. l ,v
